I'm going to stick with the F-body PCM, and have the VATS removed.
I've heard the F-body headers will fit an A-body, but they're pretty rusty, so I bought some Edelbrock ceramic coated stainless steel stepped headers.
Yes on the Hydraulic clutch.
Fuel system I wasn't happy with anyway (Tanks Inc. drop-in sump in stock tank), and it'll only support about 400hp... I plan on making about 500hp, so I'll be upgrading to one of those new "Vaporworx" tanks from Rick's so I don't have to worry about starvation problems on a roadcourse. It's way expensive, but I did it the "cheap" way last time, and was never happy with it.
That shifter is a B&M... I hope I can use it, I like the throw and the "defined" feel of the gates.
